Giới thiệu Bảng mạch khuếch đại âm thanh kỹ thuật số 2x15W Bluetooth 5.0 mini hai kênh AUX

2x15W Bluetooth-compatible 5.0 Digital Power Amplifier Board Module Two-channel Stereo Mini Digital Amplifier Support AUX Bluetooth-compatible Input
100% brand new and high quality
Features:
High-performance power amplifier board, dual-channel output, high efficiency and stability.
With overvoltage, undervoltage, overheating, DC detection, and short circuit protection functions.
Only when the voice frequency input is sufficient and the power supply voltage/current is sufficient, will there be sufficient output power. The higher the power supply voltage, the higher the relative power, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the larger the horn ohms, the smaller the relative sound power.
